{"product_id":"9780711037700","title":"How to be a Railway Signalman","description":"The heritage railways around Britain today operate hundreds of miles of  track. The role of signalling on these railways is vital in enabling them to  operate their services safely. This is the first guide to be published aimed  specifically at those who wish to learn how the signalling operates on the  heritage railways.  The reader is given a background history of the  development of railway signalling since its beginnings in the 19th century  but the book also gives the reader practical advice on the operation of the  signalling. Although the practices vary from railway to railway according to  the different traditions and the variations in the equipment, the principles  are followed by all. This book will give examples of the range of signalling  to be found on the heritage railways in the UK as well as explaining the  rules of signalling that are established on all railways.  This book will be  an indispensible manual for all those wishing to take up railway signalling  on one of the main heritage railways in Britain as well as being of interest  to all those with a more general interest in the operation of railway  signalling.","brand":"Dave Waldon","offers":[{"title":"Default Title","offer_id":45809971724606,"sku":"9780711037700","price":0.0,"currency_code":"ZAR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4357\/7662\/products\/9780711037700.jpg?v=1707312843","url":"https:\/\/exclusivebooks.co.za\/products\/9780711037700","provider":"Exclusive Books Online","version":"1.0","type":"link"}
